Abstract

A coating system (16) for an aircraft component (18) is described herein. The component (18) includes a substrate (28) having a surface (30) for the application of the coating system (16). The coating system (16) includes a diffusion barrier coating layer (20) disposed on the substrate surface (30). A bond coating layer (22) may be disposed on the diffusion barrier coating layer (20). The diffusion barrier coating layer (20) may be formed from a first MCrAlX alloy (24), where M includes, for example, cobalt and X includes, for example, yttrium. The bond coating layer (22) may be formed from a second MCrAlX alloy (26), where M includes, for example, nickel and X includes, for example, one or more of yttrium, silicon, or hafnium. The diffusion barrier coating layer (20) and/or the bond coating layer (22) may have a microstructure that includes gamma and beta phases.
